• The Philippines is an archipelago located in Southeast Asia
• Map


  A two-dimensional drawing that can be used on flat surfaces and can be easily carried
• Globe


  A three-dimensional representation of the spherical shape of Earth
• A unique feature of a globe is Earth's tilt with respect to its north and south poles
• A globe also represents Earth's position relative to the sun
• Latitudes


  Lines that run horizontally from east to west, parallel to each other
• Equator


  The latitude that cuts the Earth in half, dividing it into northern and southern hemispheres

• Geographic coordinate system


  Imaginary intersecting horizontal and vertical lines that form a grid to determine the locations of different places on Earth
• Latitudes


  Lines that run horizontally from east to west, parallel to each other
• Equator


  The latitude that cuts the Earth in half, dividing it into northern and southern hemispheres
• Longitudes


  Lines that run from north to south
• Prime meridian


  The longitude that passes through Greenwich, England, read as 0° longitude
• Antemeridian


  The longitude opposite to the prime meridian, read as 180° longitude
• Coordinates


  The intersection of latitude and longitude that determines the location of a place
• Locating a specific place on a map or globe


  1. Provide the latitude that intersects the location

  2. Provide the longitude that intersects the location

  3. Merge the latitude and longitude values along with their directions
• Large areas like the location of countries can be represented by using a range of longitudes and latitudes
• Latitude


  Imaginary horizontal lines used to determine the exact coordinates of a place on Earth
• Longitude


  Imaginary vertical lines used to determine the exact coordinates of a place on Earth
• Manila has a latitude of 14.5° N, 121° E.
• Determining longitude


  1. Use the prime meridian as the reference point

  2. Determine the distance from the prime meridian

  3. Write if the place is found E (east) or W (west) from the prime meridian
• Coordinates


  The intersection of latitude and longitude that represents a specific location
• Determining coordinates of a location


  1. Enclose the place in an imaginary box

  2. The upper and lower boundaries serve as the range for its latitude

  3. The right and left boundaries serve as the range for its longitude
• The coordinates of the Philippines is 116° to 126° N, 5° to 20° E
• Finding coordinates of a location


  1. Find the latitude that intersects the location

  2. Find the longitude that intersects the location

  3. Merge the latitude and longitude values
• Global Positioning System (GPS)


  A system that uses satellites to determine the location of a GPS receiver
• Geographical Information System (GIS)


  A system that uses satellites and computer software to gather and display data about the Earth's surface
